About This Data
Source: NYC 311 Service Requests (NYC Open Data, dataset erm2-nwe9), filtered to agency HPD. HPD violation data from dataset wvxf-dwi5. Date range: January 1, 2024 to present. Updated daily.
Building matching: Complaints and violations are matched to buildings via BBL (borough-block-lot identifier) from the NYC Department of City Planning PLUTO dataset. 834,400 buildings seeded from PLUTO; 1.9M complaints matched.
Batch-closure rate (28.4%): Heat complaints closed in batches of ≥5 at identical timestamps to the same building — a proxy for HPD's duplicate-consolidation mechanism, where multiple complaints for the same building-wide condition are merged and closed simultaneously. This figure was computed from a June 2026 batch analysis; see the full methodology in our phantom closures investigation.
Dashboard stats: All aggregate statistics (complaint counts, borough breakdown, top buildings) are pre-computed nightly and cached in the database. Last computed: June 14, 2026. Stats refresh daily at 8am UTC via the automated sync workflow.
Limitations: Pre-2024 complaint history not included. Per-building complaint rates reflect buildings with at least one complaint, not all buildings. Correlation between closure rates and violation rates does not imply causation.
